SPECIFICATION forming` part of Letters Patent No. 264,598, datedSeptember 19, 12382.

(No model.)

To all whom it may concern .Beit known that I, BENJAMiN F. ALDRIDGE, ofHill Springs, in the county of Henry and State of Kentucky, haveinvented certain new and useful Improvements in Churns; and I do herebydeclare the following to be a fullclear, and exact description of theinvention, such as will enable others skilled in theV art to whichitpertains to make and use the' same.

churns, and it consists in certainY details in construction andcombination of parts, as will be more fully described, and pointed outin the claims.

In the accompanying drawings, Figure 1 is aperspective view of myimproved churn. Fig. 2 is a view ofthe flasher-rod, showingthe manner ofsecuring theoperatingstraps thereto; and Fig. 3 is a view of theadjustable dasher. A represents a suitable base, to which. theuprightstandardBisremovablysecured. This standard B is provided atitslower endwith the round tenon al,which latterpasses through asuitableopening in the said base and is secured therein by the wedge b. Thisstandard is strengthened and heldin position by the side braces, C,which latter are secured at one end to the sides of the base and attheir opposite ends 'to the sides ofthe standard B. This stan dard isprovided ucar the upper end thereof with the two horizontal parallelbars D D', the lower one, D, of which rests on the shoulders c, and issecured thereto by screws. These bars rest over the base A and are eachprof vided on their outer ends with the half-bearings E, in which thedasherrod F rests and moves.- This dasher-rod F is provided near itsupper end with the circular enlargement or drum G, which latter restsbetween the bars D and Dl and prevents the said dasher-rod from movingvertically, and is also adapted for the attachment of theoperating-straps I. This enlarged portion or drum G is provided with therecesses d, situated in different hori-Y zontal planes, the oppositeside walls of which incline in opposite direction, or incline in thedirection the respective straps take after they leave the recesses.

A projectinglug,f, is secured in the inclined side wall of each recess,but does not project up above the true circumference of the drum so .asto interfere with and wear away the oper-l ating-straps which aresecured thereto. These operating-strapsI (two in number) are securedrespectively to the operating-levers, while the opposite end s thereofpass around the drum in opposite directions, and are secured thereto bythe lugsf. The outer or free ends of these straps are iirstrintroducedinto their respective recesses, which completely protects the said ends,while they are secured to the said dasher- My invention relates to animprovement in rod by the lug'sf, 'which latter pass up through openingsnear the end ofthe straps. This construction serves to protect the endof the straps V'but would also give an irregular or jerking motion to.the dasher, which is not desirable. These straps pass around the drumon the dasher-rod in opposite direction, and are secured to theperipheries of the semicircular disks K by the screws g. Thesesemicircular disks K are situated indifferent horizontal planes, theupper being ina plane with the top-strap attachment on the dasher-rod,while the lower one'is in a plane with the lower-strap attachment on thedasher-rod. These dasher-rod attachments and semicircular disks areseparated suiciently so as to prevent the straps-from rubbing orinterfering with each other duringv the operation of the machine.

L and L are horizontal operating-levers, pivotally secured to thestandards B and connected together by the loose handles M. The

lower lever, L, rests on the bar D, while the upper lever, L', issituated above the bar D and rests on a shoulder (notshown) formed nearthe upper end ot' the standard B. The upper end of the standard B passescentrally through the two levers L and'L, and the two semicircular disksK are secured to the said lower lever, L, on opposite sides ot' the saidstandard. The lower semicirculnr disk is secured directly to thelever L,while the upper semicircular disk K is rigidly` secured to abearing-block, h, which latter is secured di. rectly to the lever L. Asthe two levers L L are connected together by the vertical handles- M, itfollows that as the handles are moved in the arc of a circle around thestandard B `both levers L L are also caused to move simultaneouslytherewith in the'same direction. This construction forms a solid andsubstantial frame and prevents the handles M from being IOO bent orbroken off, while the connections be tween the said levers and standardare such that there is little or no friction produced while operatingthe machine.

The straps I are so connected to the drum that when one is wound thereonthe other is unwound, and as the vibrating` motion is coutinned thestraps are successively wound and nnwound on the drum.

A fan, N, is secured to the top lever, L', to fan the operator while thechurn is in operation, and a. second fan or brush, N', is secured* tothe dasher-rod, just above the head of the churn, to prevent dust ordirt from falling into the said head, and also to keep oti' insects andi'lies. The lower part of the dasher-rod is t'ormed square, which notonly assists in converting the cream into butter, but aftords increasedbearings for the extensible dashers, which are secured thereto. f

The dasher-rod F is provided with two openings, i, through the same,through which the horizontal barsj ofthe flasher() pass. These bars jare provided with the horizontal beaters r, secured on opposite sidesotthe said bars, as shown, so as to present as much beatingsurtaee aspossible. The inner ends ofthe barsj are adapted to pass through theopenings i from opposite sides ot' the dasher-rod, and rest one abovethe other, and are secured in the position by the screws l, which passthrough one side of the dasher-rod and between the two bars t', and actas a wedge which holds them securely7 iu position. By simply removingthe screws l the dasher can be increased or decreased in width, soas tosuit the churn P, which can be of any size and construction.

'lhe horizontal bars eau be elevated, so as to accommodate churns ofditferent sizes, and the standard B can be secured to any suitable basein anysuitable manner. The construction previously described, however,answers all the necessary purposes.

My improvement is simple in construction, is strong and durable in use,and can be manufactured at a small initial cost.

It is evident that slight changes in the construction and relativearrangement of parts might be resorted to withoutdeparting from thespirit of my invention; and hence I would have it understood that I donot limit myself to the exact construction of parts shown and described,but consider myself' at liberty to make such changes and alterations ascome within the spirit and scope of my invention.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

l. In a vibrating churn, the combination, with a standard having twooperating-levers pivoted thereto, handles connecting the said levers atopposite ends, and two semicireular disks rigidly lsecured t0 one otsaid levers on opposite sides ot' the standard in different horizontalplanes, ot' a dasher-rod provided with a drum, and operating-strapsplaced in dilierent horizontal planes and adapted to connect the saidsemicircular disks with the said drum, substantially as described.

2. The combination, with the dasher-rod provided with two openings, of atwo-part dasher, the horizontal bars of which are adapted to passthrough said openings and rest one above the other therein, and screwsadapted to pass between said horizontal bars and hold them together.substantially as described.

In testimony whereof I have signed this specification in thepresence oftwo subscribing,r witnesses.
